摘要
在分析、比较国内外各种同类液压桩锤优缺点的基础上,设计一种新型氮爆式液压桩锤产品。该产品采用气液联合控制,将氮气爆炸能和锤头的重力势能作为对桩的打击能,并实现冲击能和打击频率的无级调节,从而降低制造成本,提高设备的适应性。最后应用状态空间法对冲击过程建立数学模型,并进行仿真分析。首台ZCY70样机的实验成功,证明其优越性和仿真分析的正确性,并为自主研发适应我国国情的液压桩锤奠定技术基础。
On the base of analysis and compare to various domestic and overseas similar hydraulic piling hammer, a new kind of hydro-pneumatic piling hammer was designed. It is pneumatic and hydraulic united controlled, put the energy of nitrogen explosion and the hammer＇s gravity on the pile, and also can adjust the impact and frequency in stepless, thus reducing manufacturing costs and improving its adaptability. At last, establish mathematical model for impact process with the equations of thermoelasticity and analysis its simulation. The developed prototype of ZCY70 is demonstrating the feasibility and outstanding character of the scheme. It may provide the technical foundation for developing the equivalent products in our country.
